Having some fun with Dyna-Cab and speaker phase alignment.
Dynamic in the middle, condensor and ribbon panned hard left and right.
This phase alignment (dynamic 10mm closer than the other two) gives the Middle + Bridge cluck a nice finish on top....
Apparently, according to the wavelength calculator, at 68 degrees Fahrenheit (20 Celsius) and sea level, the wavelength of 20mm (double the 10mm distance difference to give 1/2 wave cancellation frequency) corresponds to 17.15kHz, which is where it nulls the side mics a bit. You wouldn't think you could hear a difference at that frequency, given it's guitar speakers....
Incidentally, I was able to get the dynamic to sound close to the ribbon and/or condensor by simply poking around the grill cloth until i fleshed out the bottom and tamed the top just right. Note the positions in the first pic. They all sound fairly similar in those positions. The condensor and ribbon both have extended low frequencies, but the distance removes the proximity bump, and the dynamic being right on the grill cloth lets the proximity bump help its weak lows....
